Büchner flask

Abstract: The utility model provides a simple and easy suction filtration experimental apparatus, includes buchner flask, support, buchner funnel, ball -milling clamp, waste liquid jar and oil pump, and buchner flask places on the support, and buchner flask bottom lateral margin fixedly connected with fluid -discharge tube is equipped with the plug valve on, and the flowing back pipe is connected through first rubber tube to the waste liquid jar, buchner flask bottleneck lateral margin fixedly connected with three -way cock valve, three -way cock valve right side is equipped with the suction filtration interface, and the oil pump passes through the suction filtration interface on second rubber tube union three way cock valve right side, and three -way cock valve downside is equipped with the pressure release mouth, buchner flask's bottleneck is greater than the interior ground of glass of bottom diameter for the top diameter. The utility model relates to a rationally, simple structure, provide a simple structure, suction filtration and can conveniently control a simple and easy suction filtration experimental apparatus of negative pressure fast.

Abstract: To measure the solids content of a sample of water, the sample is filtered using a filter cup 9 having an integral filter paper 10 therein to which suction is applied via a Buchner flask, and the whole cup and filter paper unit is weighed before and after. The process can be automated, the cup 9 being easier for robot arms to handle than a separate wet filter paper.

Abstract: The utility model provides a pressure -reduction filter device, including the suction filtration pump, buchner flask and funnel, the air tube outlet that takes out of suction filtration pump is connected with the one end of many spinal branchs pipe, the other end of branch pipe is connected with buchner flask's extraction opening, be equipped with the stop valve on every spinal branch pipe, the funnel is installed on buchner flask's bottleneck, still include fixed baseplate, the last buchner flask socket that is equipped with of fixed baseplate, buchner flask socket inboard is equipped with jack catch clamping mechanism, buchner flask inserts among the jack catch clamping mechanism, still include hollow base, the hollow base top is fixed with the recess, the recess inboard is equipped withthe rubber pad, the recess bottom is equipped with the through -hole, through -hole and hollow base intercommunication, the suction filtration pump is installed in the recess. The device can carry out the suction filtration to a plurality of buchner flask simultaneously, and is efficient, buchner flask fixing device is equipped with, the turnover of suction filtration in -process buchner flask can be prevents, damping device, the vibrations of suction filtration in -process suction filtration pump are less, need not the filtrating among the manual buchner flask of falling, it is easy and simple to handle, can prevent that the outage takes place the suck -back suddenly, the security is higher.

Abstract: The utility model relates to a determination apparatus for calcium hydroxide content in a cement base material. The determination apparatus comprises a heating-cooling system and a titration system, wherein the heating-cooling system comprises heating devices, flasks, serpentine condensing pipes, rubber pipes, glass tees and shelves, the titration system comprises a titrator, a Buchner flask, a Buchner funnel and a magnetic stirrer, the flask is arranged above the heating device, the flask port is connected with the serpentine condensing pipe, the serpentine condensing pipe is fixed on the shelve, and is clipping by using a clip, the clip can move up and down along the shelve, the rubber pipe and the serpentine condensing pipe are connected through the glass tee, a serpentine pipe with a through hole, a liquid inlet and a liquid outlet are arranged inside the serpentine condensing pipe, the titrator comprises a titration pipe and a solution bottle, the upper end of the Buchner flask is provided with a thick neck for placing the Buchner funnel, a wood plug is connected between the Buchner flask and the Buchner funnel, and the side surface of the Buchner flask is provided with a narrow neck. The determination apparatus has characteristics of simple use, accurate measurement and low cost.
